Endosperm development

During our long lasing interest in nuclear endosperm we have addressed a number of aspects, including the biochemistry of starch synthesis, cell biology, genetics, developmental biology as well as the transcriptomics of barley, rice, maize wheat and Arabidopsis. Highlights of our findings include the discovery of the cytosolic AGPase in barley endosperm, identification of the aleurone specific Ltp2 promoter, radial nuclear based microtubular cellularization of early nuclear endosperm, the DEK1 dependent positional signaling underlying aleurone cell formation, development of an in vitro organ culture system for maize endosperm and the asymmetric contribution of the A, B and D genomes to the unique properties of hexaploid bread wheat.
